When Eric Fréminger,
manager of a big company is ruined by his scrupulous associate, Babin, he decides
to end it all. One evening he tells this to Helene, his wife and Robert, her driver.
But if she wants to cash in the insurance money of 300 million, it has to look
like a crime. Fréminger shoots himself in the head. Hélène begins an affair with
Robert and hires a young maid, Jeanne. She tells her that her husband lives as
a recluse because of his creditors, but in fact they keep his dead body in a cold room.
One evening, Robert pushes the car of Fréminger in a creek and hides the body
in the undergrowth. Thanks to the testimony of Jeanne, the police has to believe
Helene and Robert are innocent. At this point in time Babin reappears to recover
significant papers. Helene believes that he would make an ideal culprit. To compromise
him, she invites him to the villa and requests that Robert argues with her. But
he hits her to hard and accidently kills her. Babin notifies the police who discover
the body of Helene and arrest Robert with a double accusation of murder...
